HAND CHEMICAL FIRE-EXTINGUISHIER.

Speeication of Letters Patent.

Patented July 16, 1907.

Application filed October 2,1905. Serial No. 280,949.

To 'all whom, 'it may concern:

Be it known that ORLANDO J. CHILDS and JAMES H. CoRBn'r'r, of Utica, inthe county of Oneida and State of New York, have invented certain newand useful Improvements in Hand Chemical Fire-Extinguishers; and they dohereby declare that the following is a full, clearand exact descriptionthereof, which will enable others skilled in the art'to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

The object of our invention is to provide an improved hand chemical fireextinguisher, wherein provision is made for simultaneously lclosing theacid receptacle and the main tank or receptacle, so that in case theextinguisher is upset or subjected to much movement or agitation, as inmoving cars or vehicles, the contents of the receptacles will not bewasted or commingled; and the extinguisher will be so simple as to bereadily operated by those unfamiliar with it.

i A further object is to, provide 'in such a fire extinguisher aconstruction that has a number of features which add to its utility,-facilitate its construction and increase its efficiency. l

Figure 1 of the drawings shows a sectional view of the tank or bodyportion of the extinguisher, together with a side elevation of the capfor thesame, the acid receptacle and its coperating parts. Fig. 2 showsthe same as Fig. l, with the movable parts operated to a differentposition and the acid bottle or receptacle removed. Fig. 3 shows on anenlarged scale details ofthe construction mostly in section, with themovable parts adjusted to the positions which close the' dischargepassage from the main receptacle, and close the inner or acidreceptacle. Fig. 4 shows the same, with the parts adjusted to open thedischarge passage from the main receptacle, and also open the in,

ner or acid receptacle. Fig. 5 shows a partial inner face view of thecap or cover of the main receptacle, together with certain details oftheconstruction; Fig. 6 shows in `vertical section certain other details ofconstruction.

Referring to the reference letters and figures in a more particulardescription of the construction, 1 indicates the main tank or receptaclewhich ordinarily will be nearly full of a solution of soda in water. Theupper end of this receptacle will be closed by a screwthreadedvv cap2,`which cap will preferably be provided with a handle 3 by means ofwhich the extinguisher can be carried or handled, and which also servesto turn on `or turn off the cap from the receptacle, the same requiringto be removed for the purpose of filling the receptacle or changing thesolution.

Secured to the inner face of the c'ap 2 is a bottle or "inner receptaclehanger 3, consisting of a U-shaped rod extending downwardly from the capa suflicienl. distance, and provided with a ring 4 secured therein, towhich is hinged at points at right angles with the plane of the hanger 3a U-sllaped retainer 5, the hanger 3 preferably `being made of smallrods or large wire, while the retainer 5 will be made of smaller wire orrods, and at the lower end of the hanger 3 the same is provided with anotch or indentation a, which receives the lower end of the retainer 5and holds it in normal closed position, except when forcibly moved.There is enough spring or elasticity in the retainer 5 to allow it toengage in or become disengaged from the notch a. When the retainer 5 isswung to one side, as shown in Fig. 2, or further, the acid bottle orreceptacle 6 can be placed in position by inserting the neck end throughthe ring 4 and swinging the bottom into axial line with the hanger. Theretainer 5 will then be moved into its normal holding position when theacid receptacle will be held firmly in place. On the ring 4 there areprefere-.bly .provided projections 4-a which engage on the shoulder ofthe acid receptacle or bottle and prevent it moving toward the capv 2when the extinguisher is inverted.

The upper-portions of the hanger 3 are preferably broughtcloser'together than the portions at the lower end, so as to form slidesor ways 7, in which, or on which, is mounted to slide in a verticaldirection the stopper carrier V8. This stopper carrier 8 has attached toits lower end the stopper 9 adapted to close the mouth of the acidbottle or receptacle 6. The stopper is preferably jointed or hinged tothe carrier 8, so that it is free to find a perfect seat on the mouth ofthe bottle when in closed position.

For the purpose of operating the stopper carrier 8, there is provided onthe lower end of the stop cock core l0, which is suitably extended toprovide a cylinder head IO-a therefor, a pair of spiral projecting ribsll in the nature of screw-threads, which engage in notches 8--a in theupper portion of the stopper carrier 8. When the Core l0 is turned inone direction the spiral ribs 11 serve to force the carrier 8 together,with the stopper 9 down until the stopper seats firmly on the mouth ofthe receptacle 6, thereby closing it against the escape of its contentswhen the extinguisher is inverted or otherwise.

The stop cock core l0 is provided with a passage b, which, when theYoperating handle 12 thereof is placed in one position, is adapted toopen the passage from the main receptacle 1 to the discharge passage c,through the nozzle 14. The arrangement of the spiral ribs l1 and thestopper carrier 8 with reference to the passage b is such that thecarrier and stopper will be in their upper position when the passage bregisters with the `into the position shown in Figs. 1 and 3, that boththe the extinguisher is then inverted which allows the `porarily stoppedby partially turning the stop cock passage c, etc., so that the mouth ofthe receptacle 6 will at that time be left open. It is also obvious thatthe stop cock core 10 may be turned by means of the handle 12, so as toforce the stopper and stopper carrier down untilthe stopper vcloses themouthv of the receptacle 6. In so doing, the passage b is moved out ofregistering position with the otherA passages, so that the escape of thecontents of the-main receptacle 1 through the nozzle 14 is shut off.This passage is shut off even by a partial turn of the stop cock, andbefore the stopper has closed the acid receptacle 6. Over the inner endof the passage to the nozzle 14 there is provided a strainer 15Withlholes small enough to prevent any particles entering the passagethrough the nozzle 14, which will not readily pass therethrough andwould otherwisehe liable to obstruct the passage.

It is evident that when the stop cock core 10 is turned acid receptacle6 and the passage through the nozzle 14 from the main receptacle aresecurely closed, and in case the extinguisher should become overturnedor be otherwise violently agitated, the contents of neither receptaclecan escape or be wasted.

To put the extinguisher into operation, the stop cock core 10 is turnedinto -the position-shown in Fig. 4,' which, at the same time, opens thepassage through the nozzle 14 and the mouth of the acid receptacle 6,and

acid and contents of the main receptacle to produce a chemical action,creating a pressure of gas which forces the liquid contents of the mainreceptacle out from the nozzler14. The discharge through the nozzle 14,when the extinguisher is in inverted position, can be temcore 10, thechemical action ceasing when a sufcient pressure is attained in the mainreceptacle. It may also be noted that after checking the discharge fromthe nozzle 14 in this way, if there is no further use for theextinguisher it can be placed in its normal upright position and thestop cock again opened, relieving the pressure from the receptaaclethrough the nozzle 14, the acid not discharging at such time, on accountof the upright position of the acid receptacle.

In order to facilitate the attachment of the upper ends of the hanger 3to the inside of the cap 2, there is preferably formed on the inner faceof the c'ap halfsleeves 20 and malleable ears or projections 21-21. Onthe upper end of the hanger 3 there are provided right-angle bends S-a.When these are inserted in the half-sleeve 20 and between the ears 21,as shown, the malleable ears 21 are clenched over the projections 3-'a,readily securing it inf position. In addition to this, solder can beapplied if desired. l

It will be noted that the stop cock core 10 is of a conical form, withthe smaller end outward, and the socket S in the cap 2 is arranged toreceive t-he same;

.` and that the pressure on the stopper 9, which serves to close themouth of the receptacle 6, also serves to force the stop cock morefirmly into its socket, and also close that more firmly against anytendency to leak. When the stop cock is moved towards its openingposition, the pressure which forces the same into its socket isrelievedto some extent and it may operate more. freely. The pressurecreated in the main receptacle also serves to force the stop cock core10 into its seat and obviate any tendency to leak, and the wholearrangement facilitates the construction and assembling of the parts.

Numerous modifications and changes in and from the construction hereindescribed may be made Withoutl departing from the spirit of ourinvention,

What we claim as new and desire to secure by Letters Patent is:

1. The combination in a hand chemical fire extinguisher of a mainreceptacle, a removable cap adapted to close the opening yinto the mainreceptacle, a removable inner receptacle, a hanger lsupporting the innerreceptacle from the, cap, a discharge passage through the cap from themain receptacle. a stop cock controlling said discharge passage, meansfor manually operating the stop cock, :1 stopper for closing the innerreceptacle and means operating in connection with the stop cock foropening and closing the stopper'r substantially as set forth.
